IMPROVEMENT IN STEAM-PUMPS.

Specification forming part of Letters Patent No. 126,536, dated May 7, 1872.

SPECIFICATION.

I, HENRY EPPING, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain Improvements in the Construction of Steam-Pumps and the like, of which the following is a specification:

Nature and Objects of the Invention.

This invention relates to an improvement in the construction of that class of steampumps wherein is used a frame77 between the steam-cylinder and pump-barrel, for the purpose of connecting the two. My invention isl Description 0f the Accompanying Drawing.

Figure 1 represents a perspective view of my improved steam-pumping apparatus. Fig. 2represents a perspective view of the ,intermediate oblong connecting-frame detached. Fig. 3 represents an end view of said frame.

General Description.

To construct a pump I make the steam-cylinder A and pump-barrel B in any of the wellknown ways, and provide each with requisite passages and valves, induction and cduction ports and pipesin short, with all the usual appliances and appendages incident to such apparatus; but in order to carry out the object of my invention, the oblong intermediate connecting-frame C, with its bearings e e for the ily-wheel shaft S, and bearin gs n n for the rock-shaft P, slide-bearings K K for the crosshead W, and with a circular head, B, on its opposite ends, of a size requisite to it, the one the end of the steam-cylinder, and the other the pump-barrel, and each provided with a ange,

d, to secure the same in place, is constructed in one piece, as represented in Fig. 2, by casting the same in a properly-formed mold in the usual way of making such castings, and of which no description is herein deemed necessary; the object being to avoid the numerous tittings that would otherwise be required if made in several pieces or in any other form.

When the steam-cylinder A and pump-barrel B are bored out and their ends faced off, the frame C is to be suspended longitudinally in a lathe, and a hole for the pistonrod drilled through the center of both ends. The heads R are then to be turned to tit, the one the bore of the steam-cylinder, and the otherthepump-barrel, and correspondingholes drilled through their several ilanges, so that when the parts are brought together, as shown in Fig. 1, they may be united in a most substantial manner by means of screw-bolts passing through both.

This construction, combination, and arrangement of the parts speciiied brings and secures the pump-barrel always on a perfect straight and axial line with the bore of the steam-cylinder, and is easier itted, and less liable to become deranged than when united in any other way.

This construction of the oblong connectingframe O enables me to place the y-wheel shaft S, rock-shaft P, and their respective bearings c and n, together with the slide-bearings K K 0I" the cross-head W, in a horizontal plane above the axial line of the piston-rod X, by simply depressing the central portion of the cross-head W at that point where the pistonrod X, passes through it, by which arrangement all the operating parts of the apparatus between the pump B and steam-cylinder A are brought above the frame C, and are thereby more easily got at for repairs or other purposes.

I may here state that although this apparatus is intended for forcing or pumping liquids, yet such is its construction that it may be applied with equal facility to the blowing or forcing atmospheric air or gases under pressure.

head W, constructed, arranged, and ycombined. with a steam-cylinder, A, and pump-barrel B, in the manner shown and set forth.
